Rollback tokens aren't universal: they are not only different for every login, but also depend on the title of the page and the name of the user whose edits are to be rolled back. For MediaWiki 1.23 or earlier, follow these instructions:

Respuesta

The Response section below is for the final POST request, to revert the edits to the Sandbox page.

{"rollback":{"title":"Sandbox","pageid":94542,"summary":"Reverted edits by [[Special:Contributions/41.190.3.231|41.190.3.231]] ([[User talk:41.190.3.231|talk]]) to last revision by [[User:Didicodes|Didicodes]]","revid":381084,"old_revid":381083,"last_revid":381070}}

Permisos

Rollback requires both the editpage and the rollback right on the target page; currently, this means that OAuth consumers, bot passwords etc. require both the editpage and the rollback grant – rollback alone is not enough!
